Quick answer
SkipperCalc has 1 sourced Outer Reef configurations in the picker. Use them as a starting point when you do not know your exact fuel burn, and replace the figure with your measured burn when you can.
- Outer Reef 860 · 2 × Caterpillar Caterpillar C18
Practical rule: compare L/nm or €/nm, not only L/h, because speed changes cost per mile.
Calculate with a listed configuration
Open “Choose my boat”, select the brand and model, and the calculator will use interpolated fuel burn inside the published speed range.
